The central idea of Memento is fascinating in that it is a thriller built around a main character who cannot remember anything for more than a few minutes. That is combined with a reversed narrative structure where we see the ending and as we go backwards in time we realize that we know less and less about the character and the situations. It’s great to watch and figure things out and the repetition of scenes works well too. I should have seen this film a while ago, but for some reason I just didn’t get around to it. Playing with what we see and what we know and causality is something that works very well in a film. It’s a gimmick, but it is done so skillfully that we admire the way that it plays out.
